Javascript &引用；未定义的步骤参考“；在WebStorm中尝试引用TypeScript步骤定义代码时

在基于cucumber量角器typescript逻辑实现一些测试脚本时，我遇到了一个问题：我的小黄瓜找不到步骤声明：

步骤定义用TypeScript编码。但是，我的所有测试都编译并运行成功。

当我试图手动创建步骤定义文件时，没有创建TypeScript文件的选项，只有JavaScript：

以下是我的步骤定义示例：

defineSupportCode(({Given, When, Then, Before}) => {
      let search: Search;

   Before(() => {
       search = new Search();
   });

   Given(/^User on the angular site$/, async () => {
       let title = await browser.getTitle();
       return expect(title).to.equal('Angular');
   });

   When(/^User type "(.*?)" into the search input field$/, async (text: string) => {
       await search.enterSearchInput(text);
   });

   Then(/^User should see some results in the search overlay$/, async () => {
       await search.getSearchResultItems();
       let count = await search.getCountOfResults();
       return expect(count).to.be.above(0);
   });
});

还有我的黄瓜档案：

 Feature: Search
   As a developer using Angular
   User need to look-up classes and guidelines
   So that User can concentrate on building awesome apps

 @SearchScenario
   Scenario: Type in a search-term
   Given User on the angular site
   When User type "foo" into the search input field
   Then User should see some results in the search overlay

我的存储库结构：

/features
   /steps
    searchSteps.ts
 search.feature
/pages
 search.ts

有人知道如何解决这个问题吗？

不幸的是，WebStorm不支持用TypeScript编写Cucumber.js测试。请投票支持TypeScript，如有任何进展，请予以通知
